The original price of a ski jacket was $250. It was on sale at a 25% discount. Arianna had a coupon for an additional 10% off the sale price. What price did Arianna pay for the ski jacket?

Original Price = $250

Discount = 25% of $250 = 0.25 x 250 = $62.50

Price after discount = $250 - $62.50 = $187.50

Addition discount = 10% of $187.50 = 0.1 x 187.5 = $18.75

Price after additional discount = $187.50 - $18.75 = $168.75

Answer: $168.75
